Stainless Steel 446 Nuts And Bolts<\/strong>, which is available in different shapes and sizes at reasonable price to our customers. At the solution treating temperature, 1900 Degree F, Stainless Steel 446 Hex Head Bolts is austenitic but undergoes transformation to a low \u2013 carbon martensitic structure during cooling to room temperature. When frequent thermal cycling is involved, Stainless Steel 446 Hex Head Nuts is resistant to about 1850 Degree F, where this transformation is not complete until the temperature drops to 90 Degree F.<\/span><\/p>\n<\/span><\/p>\nThe high chromium and relatively low nickel content of Stainless Steel 446 Square Bolts provide good resistance to high temperature Sulphur bearing atmospheres. Stainless Steel 446 Square Nuts has only moderate resistance to carbon absorption and is not suggested for use in highly carburizing atmospheres. Prolonged exposure to the 1100 Degree F \u2013 1600 Degree F temperature range in Stainless Steel 446 Eye Bolts will cause some sigma to form, lowering room temperature ductility and impact resistance.<\/span><\/p>\nBecause Stainless Steel 446 Eye Nuts is an air hardening steel, it must be given a high preheat, at least 350 Degree F \u2013 400 Degree F before welding, and immediately given a full anneal before the weldment cools. Otherwise Stainless Steel 446 U-Bolts will harden, and cracking is likely, where this hardening treatment also tempers the martensitic structure, increasing ductility and toughness.<\/span><\/p>\n\n\n\n\nSS 446 Bolt\/Nut Specifications<\/strong><\/span><\/h3>\n<\/td>\n<\/tr>\n\nSpecifications<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\nASTM A 193 ASME SA 193<\/span><\/td>\n<\/tr>\n\nStandard<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\nDIN, ASTM, BS and all International Standards<\/span><\/td>\n<\/tr>\n\nLength<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\n3 mm to 200 mm<\/span><\/td>\n<\/tr>\n\nSize<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\nM3 \u2013 M56 | 3\/6\u2033 to 2\u2033 | Custom Sizes<\/span><\/td>\n<\/tr>\n\nType<\/strong><\/span><\/td>\n:<\/strong><\/span><\/td>\nHex Head Bolts, Square Bolts, U bolts, Eye bolts, T bolt, Hex Bolt, Lag Bolts, Counter sunk Bolts, Hex Head nuts, Square nuts, Lock nuts, Eye nuts, wing nuts, T nuts, Panel Nuts, Coupling Nuts, Dome nuts, Acorn Nuts.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n446 Stainless Steel Bolt\/Nut Chemical Composition<\/strong><\/span><\/h3>\n\n \n\n\nGrade<\/strong><\/span><\/td>\nC<\/strong><\/span><\/td>\nMn<\/strong><\/span><\/td>\nSi<\/strong><\/span><\/td>\nP<\/strong><\/span><\/td>\nS<\/strong><\/span><\/td>\nCr<\/strong><\/span><\/td>\nMo<\/strong><\/span><\/td>\nNi<\/strong><\/span><\/td>\nN<\/strong><\/span><\/td>\n<\/tr>\n\n446<\/strong><\/span><\/td>\nmin.<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | 23.0<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | 0.10<\/span><\/td>\n<\/tr>\n\nmax.<\/span><\/td>\n | 0.2<\/span><\/td>\n | 1.5<\/span><\/td>\n | 0.75<\/span><\/td>\n | 0.040<\/span><\/td>\n | 0.030<\/span><\/td>\n | 30.0<\/span><\/td>\n | \u2013<\/span><\/td>\n | 0.50<\/span><\/td>\n | 0.25<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nStainless Steel 446 Bolt\/Nut Mechanical Properties<\/strong><\/span><\/h3>\n\n \n\n\nGrade<\/strong><\/span><\/td>\nTensile Strength (MPa) min<\/strong><\/span><\/td>\nYield Strength 0.2% Proof (MPa) min<\/strong><\/span><\/td>\nElongation (% in 50mm) min<\/strong><\/span><\/td>\nHardness<\/strong><\/span><\/td>\n<\/tr>\n\nRockwell B (HR B) max<\/strong><\/span><\/td>\nBrinell (HB) max<\/strong><\/span><\/td>\n<\/tr>\n\n446<\/span><\/td>\n | 485<\/span><\/td>\n | 275<\/span><\/td>\n | 20<\/span><\/td>\n | 92<\/span><\/td>\n | 201<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nStainless Steel 446 Bolt\/Nut Physical Properties<\/strong><\/span><\/h3>\n\n \n\n\nGrade<\/strong><\/span><\/td>\nDensity (kg\/m3)<\/strong><\/span><\/td>\nElastic Modulus (GPa)<\/strong><\/span><\/td>\nMean Coefficient of Thermal Expansion (m\/m\/0C)<\/strong><\/span><\/td>\nThermal Conductivity (W\/m.K)<\/strong><\/span><\/td>\nSpecific Heat 0-1000C (J\/kg.K)<\/strong><\/span><\/td>\nElectrical Resistivity (n.m)<\/strong><\/span><\/td>\n<\/tr>\n\n0-1000C<\/strong><\/span><\/td>\n0-3150C<\/strong><\/span><\/td>\n0-5380C<\/strong><\/span><\/td>\nat 1000C<\/strong><\/span><\/td>\nat 5000C<\/strong><\/span><\/td>\n<\/tr>\n\n446<\/strong><\/span><\/td>\n7750<\/span><\/td>\n | 200<\/span><\/td>\n | 9.9<\/span><\/td>\n | 11.4<\/span><\/td>\n | 11.6<\/span><\/td>\n | 24.9<\/span><\/td>\n | 28.7<\/span><\/td>\n | 460<\/span><\/td>\n | 570<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nEquivalent Grades for 446 Stainless Steel Bolt\/Nut<\/strong><\/span><\/h3>\n\n \n\n\nGrade<\/strong><\/span><\/td>\nUNS No<\/strong><\/span><\/td>\nOld British<\/strong><\/span><\/td>\nEuronorm<\/strong><\/span><\/td>\nSwedish SS<\/strong><\/span><\/td>\nJapanese JIS<\/strong><\/span><\/td>\n<\/tr>\n\nBS<\/strong><\/span><\/td>\nEn<\/strong><\/span><\/td>\nNo<\/strong><\/span><\/td>\nName<\/strong><\/span><\/td>\n<\/tr>\n\n446<\/span><\/td>\n | S44600<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | 1.4762 \/ 1.4763<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n | \u2013<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nSS 446 Bolt\/Nut Application Industries<\/strong><\/span><\/h3>\n\n- Off-Shore Oil Drilling Companies<\/span><\/li>\n
